如何通过“created_time”在我的photosNSMutable数组中sorting我的图像，并获得我的集合视图以相应显示它们？

UIImage // cell.photo = self.photos[indexPath.row] as? NSDictionary cell.imageView.backgroundColor = colorWheel.randomColor() return cell } } 正如你所看到的，我正在为两个独立的用户“tuulavintage”和“wendyslookbook”为他们最近的20张照片打电话给instagram的API。 然后我parsingimageUrls的数据，把它们放到两个单独的循环中，我把这些imageUrls和更改为UIImages，并把它们放在“让照片= NSMutableArray（）”。 然后我将UIimages添加到我的集合视图单元格“cell.imageView.image = photos.objectAtIndex（indexPath.row）as？UIImage”
我也计算我的parsingNSdictionary响应像“self.photoCount = tuulavintageImageResponse.count + wendyslookbookImageResponse.count为Int”。 所以我可以告诉我的collections查看要制作多less个单元格
你也可以在这里看到（在全局主要内部）“var tuulavintageTimeResponse = tuulavintageDictionary.valueForKeyPath（”data.created_time“）as NSArray”
和这里
“var wendyslookbookTimeResponse = wendyslookbookDictionary.valueForKeyPath（”data.created_time“）as NSArray”
我parsing我的NSDictionary响应检索每个图像的unixtimecode数组，但他们没有连接。
我的问题是，如何使用我可以检索的unixtimecode在订阅视图中显示这些照片？ 我有一种感觉，我需要匹配的UIimage与他们的具体时间码，然后以某种方式告诉我的集合视图，以unixtime命令他们。
提前致谢。
以及你不必创build一个文件，但是很好的做法，保持事情的漂亮和整洁。
请尝试在相同的控制器文件中，但在您的控制器定义之外，或者在新的Swift文件中。
class IGPhotoContainer { var image: UIImage! var timestamp: String = "" //Your constructor can be like this init() { } //or overload it with 2 params for your convenience. init(newimage: UIImage, newtime: String){ this.image = newimage this.timestamp = newtime } }
如果你在一个单独的文件中执行它，请记住在新文件的开头添加这行代码。
